What is Gravity Die Casting?

Gravity Die Casting is a permanent mold casting process where molten metal—typically aluminum or copper-based alloys—is poured from a vessel into a metallic tool (die) under the force of gravity alone. Unlike pressure die casting, GDC relies on the weight of the metal to fill the mold cavity, resulting in superior mechanical properties and internal soundness.

Why Choose Gravity Die Casting?

GDC sits at the "sweet spot" between sand casting and high-pressure die casting, offering a perfect balance of cost-efficiency and quality.

  • Superior Mechanical Properties: Slower cooling rates compared to sand casting result in a finer grain structure, leading to higher strength and better heat-treatment capabilities
  • Dimensional Accuracy: Provides tighter tolerances and a much smoother surface finish than sand casting, reducing the need for extensive secondary machining
  • Cost-Effective for Mid-Volume: Ideal for production runs ranging from several hundred to several thousand units where the cost of high-pressure tooling isn't justified
  • Low Porosity: The controlled, low-turbulence pouring process significantly reduces gas porosity, making components suitable for pressure-tight applications

Our Process & Capabilities

At ICAST ALLOYS LLP, we maintain a meticulous workflow to ensure every casting meets international quality standards

Tool Design & Development

Our engineering team utilizes CAD/CAM software to design high-precision dies that optimize metal flow and thermal management, ensuring consistent quality across long production cycles.

Precision Melting

We use temperature-controlled furnaces to maintain the exact chemistry of the alloy. This prevents impurities and ensures that every batch meets the specific mechanical requirements of our clients

Expert Pouring & Solidification

Our technicians carefully manage pouring speeds and mold temperatures to eliminate defects like cold shuts or shrinkage, ensuring a dense, robust final product

Finishing & Inspection

Post-casting, components undergo shot blasting, fettling, and CNC machining if required. Every part is subjected to rigorous testing, including:

  • Spectrochemical analysis
  • Hardness testing
  • Dimensional inspection
